Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | Cecila Gallerani (mk45) | Annunciation | Madonna with the Yarnwinder after 1510 | Mona Lisa (detail) dyk | The Annunciation |

Patrick Henry Bruce
American Cubist Painter, 1881-1936 was an American cubist painter. A descendant of Patrick Henry, Bruce was born in Campbell County, Virginia, the second of four children. His family had once owned a huge plantation, Berry Hill, worked by over 3,000 slaves. Berry Hill is now a resort & conference center outside South Boston, Virginia and is now a National Historic Landmark. Berry Hill Estate originally was part of a 105,000-acre (420 km2) tract granted by the English Crown in 1728 to William Byrd II. The Civil War left the Bruce's wealth greatly diminished. Bruce began taking evening classes at the Art Club of Richmond in 1898, while working in a real estate office during the daytime. His earliest known extant painting dates from 1900. In 1902 he moved to New York, where he studied with William Merritt Chase, Robert Henri, and Kenneth Hayes Miller. By February 1904 he was in Paris, where he would live until 1933. Although his evolution toward a modernist style was gradual, his works of 1908 reveal the influence of Renoir and C??zanne, and in that year he was among the first to enroll in Matisse's school. Bruce exhibited regularly in the Salon d'Automne, and met many of the leading artists of the early twentieth century avant garde.
